CARBURETER.

State of Illinois, have invented certain new and useful Improvements in Carbureters, of which the following reference being had therein to the accompanying drawing.

This invention relates to carburetors, and has for its object the production of a ,carbureter especially designed for use in connection with internal combustion engines.

Another object of this invention is the production of a carburetor, which is'simple in construction, efficient in operation, and consists of a minimum number of parts.

With these andother objects in view this invention consists of certain-novel construc tions, combinations, and arrangements of parts. as will be hereinafter fully described and clanned.

In the drawings: Figure 1 is an elevation of. the carbureter partly in section; Fig. 2 is a bottom plan view of the same.

Referring to the drawings by numerals, 1 designates the main casing, which, has a substantially hollow' body provided with a central air inlet casing '2 formed integral with the body portion of the main casing 1. The air inlet 2 is formed, preferably, in the center of said casing and extends slightly higher than the top of the casing 1. Upon and surrounding the air inlet 2 is a top 3, which tightly fits upon the top of the casing '1, and thereby closing the upper end of the main casing 1, which contains the fuel.

The casing 1 is provided upon the bottom thereof with a plurality of depending portions 4, which are externally threaded and are adapted to receive a cap 5. The depending portion 4 is also internally threaded, and a .needleevalve member 6 is adapted to work in said depending portion and said needle-valve member comprises an elongated body provided with a tapering upper end 7 and the lower angularly-disposed end 8, which end 8 acts as a handle for the free operation of the-needle-valve 6. The cap 5 is adapted .to engage theneedle V valve 6 and prevent or limit the longitudiis a specification,

the air inlet 2, as hereinafter described. The walls 9 of the air inlet are provided upon their inner and outer sides with protruding formed therein, in which aperture works the upper end of the needle valve 6. The upper 'end of the aperture 11 is tapered, so as to receive the upper tapered end 7 of the needle valve 6, .so as to form a tight joint when it is desired to have the valve" in a preventing the mixing of the fuel with the air.

portions 10 and an aperture 11 is From the foregoing description, it will be readily seen that the flow of the fuel through the apertures can be readily regulated by turning the valve member '6 and same within the apertures or valve seats 11.

Formed upon one side'of the casing 1' is a valve casing 12, in which is positioned a suitable valve member 13,. shown indotted lines. A float 14 is positioned within the casingl and surrounds the air inlet- 2 and said float is connected to means of a connecting member 15 also shown in dotted lines, and is adapted to open or shut the valve 13 when the float 14.- raises or lowers with the 'fuel, thereby regulating the height of the fuelto be con tained within the casing 1, and it is desired the valve 13 by to have the float 14 and the valve 13 connected so as to readily close the valve 13, and cut the flow of liquid ofi therethrough, when the liquid in the casing 1 has reached the desiredheight.

The upper end 16 of the air inlet 2 is externally threaded and has an elbow connection 17 threaded thereon,. which elbow can be readily connected to the engine,' if it be so desired, for supplying the gas thereto. The elbow is .provided with apertures 18 in which is journaled a damper 18 shown in dotted lines.

The air inlet 2 is provided with a lower inwardly-extending flanged end 19, which acts as a valve seat for the plunger 20 hereinafter described. The elbow 17 is provided with an upwardly-extending portion 21 in which is formed an aperture 21 in which works a threaded member 22, which memher is provided with a head 23 for facilitatmg the operation of said threaded member 22 within the threaded aperture 21. A button or nut 24 is positioned upon the threaded member 22 between the upper end of the upwardly-extending portion 21 and the head 23 of the member 22 and is adapted to lock or hold the threaded member in a set position, after the threaded member 22 has been brou ht to the desired position for regulating t e tension of the coil spring, engaging the plun er 20 as hereinafter described. It will be obvious that when the member 22 is brought to a desired position, the nut can be threaded in the opposite direction, so as to tightly engage the upper end of the upwardly-extending oortion 21, thereby firmly locking the, threa tion. a

1 The threaded member 22 is provided with adepending-reduced portion 25, which portion works' in a sleeve 26, which sleeve supports a plunger head 20- previously mentioned. The sleeve 26 is loosely mounted upon the reduced portion 25, and said sleeve ed member in a set posiis provided, near itslower end, with spacedapart flanges 2.7, between which is adapted to be gripped the plunger head 20 thereby ing the same upon the sleeve 26. A coil spring 28 is positioned upon the res duced portion 25,-and is interposed between the threaded member' 22, which is considerablv' larger" than the reduced portion 25 anddiverges toward its lower en and the plunger head 20. Said spring tapers toward its upper end, so as to fit snugly around the upper enduof the reduced ortion so as to-vengagevthe plunger20l i It will be obviousthat'when the threaded member '22 is-rotated, so as to cause the reduced portion to move downwardly within the sleeve 26 that the-tension of the coil spring 28 will be greatl increased thereby causing 5 from said'flanges. V In operation the motor will cause a sues tion through the elbow 17, whichfas the-v engine ulsates will drive the plunger20:

From the foregcin description, it will readily be seen that I ave provided an improved carbure-ter, which is simple in construction, and which can be easily set up and 'adjusted, and I have also provided means for regulating the flow of fuel into the air Casing. 1 m

What I claim is:

A carbureter comprising a casing'forming a main fuel chamber,. a vertical central casing constituting the carbureting chamber located in said main casing and projecting discharge ends of which are located above the lower end of said casing, leading from the fuel chamber to the carbureting chamber in said central casing, needle valves passing through said fuel chamber and PIOJECtlIlg into said ports and adjustable from the bottom of. the chamber, an inwardlyhyielding disk-valve seated on said annular ange at the lower end of said central casing and closmg the opening. in the bottom thereof, a

plungerrod connected w said inwardlyyieldinggvalve and extending up through the carburetin chamber, an engine pipe connected to t e11 ing, an ad'jju'sta e elongatedtubular sleeve .dependin from said enginepipe into the upper en of; said central casing into which the plunger rod projects and is movable In testimony whereof I hereunto afiix my signature in presence of two witnesses.
